Chiral Dynamics in Nuclear Systems

Abstract

A survey is given on selected topics concerning the role of spontaneous chiral symmetry breaking in low-energy QCD, and its dynamical implications for nuclear systems. This includes aspects of chiral thermodynamics (the temperature and density dependence of the chiral condensate). It also includes an update on the theory of low-energy (s-wave) pion-nuclear interactions relevant for deeply-bound states of pionic atoms and the quest for possible fingerprints of chiral symmetry restoration in nuclear systems.Comment: 16 pages, 5 figures, Proceedings CHIRAL 02, Kyoto, Japa
